Ok I'll try again. Yesterday's post should be deleted by the administrators.
I drove my C6 2008 A6 to A&A Corvettes in Oxnard, Ca for a supercharger installation. It's about 90+ miles from where I live. When I dropped it off, about 2 1/2 weeks ago, I had to ride public transport to get home; Amtrak train to LA and city bus to Torrance, Ca about a mile away from my home. I walked the mile. This morning I did the whole thing in reverse. Walked to the bus stop at about 5:40 AM and caught a city bus. Surprisingly it was pretty full. Normally I see buses that are virtually empty. Caught the Amtrak train at Los Angeles Union station. Going into the station is like going back to the 1930's. From the Amtrac train you see California that you don't see on the Freeways. California is a pretty dry place, driving the freeways you wouldn't know it because everything is irrigated. I enjoyed my train ride. I hadn't been on a train since 1991 when I rode the trains in Europe. They travel, of course much faster, I think Amtrak was doing max at about 70+ mph.
My stone stock 08 automatic, with Andy Green's centrifugal supercharger (Vortec) pumped out 580 wheel horsepower at 6500 rpms. He spent quite a bit of time on dyno runs to get everything correct. His supercharger installation from it's appearance and attention to details looks like it came from the factory. The intercooler now completely dominates the airflow into the front grill work of the car. The supercharger intercooler installation has shrouds that forces all air into the intercooler. I think Andy advertises that he has sold 2000 of these kits and he has installed about 500 at his Oxnard garage. He is really devoted to supercharging and he also installs Edelbrock E force superchargers. He bought a supercharged Cadillac CTS-V with a supercharger that I assume is pretty much the ZR-1 Corvette supercharger, and replaced it with an Edelbrock. I didn't ask why!!
Anyhow, another trip on city buses and Amtrak and I picked up my car today to drive home. I had a discussion with Andy to learn about taking care of the supercharger, etc. I was a little wary about driving the car. Andy verified for me that some of his customers cars, leaving the facility, ended up in body shops before they ever made it home. The power from the supercharger will overwhelm the traction control feature, so you can get wheel spin and possible spin out with the extra power even with traction control active.
So...for now I just wanted to get home. I drove the car home very gently. At 70 mph, the engine is turning 1700 rpm and the centrifugal blower is just dead at that rpm. Also, at 1700 rpm, I have a lot of engine vacuum, and the blower bypass valve is open so what little pressure it generates is blown off. With my automatic I did apply a little gas pedal to accelerate and the car seemed to accelerate a little faster than stock. For just street and highway cruising, the engine response is that you have no idea that you have a supercharger. However, I never used enough accelerator to get the tranny to downshift. Downshifting awakes the supercharger. The centrifugal blower starts life at about 2500 rpm and the supercharger bypass valve closes to pressurize the intake manifold. I do plan on taking the car to a drag strip. My fastest drag strip time so far is 13.5 seconds at about 115 mph in my 69 Corvette (1975!!). This was with a L88 clone engine and old fashioned street tires. I wonder if I can get into the 11 seconds??
Because, the centrifugal blower doesn't interact much with the engine, say below 2500 rpm, the cars drivability and gas milage are not affected.
Google A&A Corvettes. Andy ships his supercharger kits world wide. Its a big 104 pound box. The precision brackets and professional intercooler and plumbing make this system work. Once again, 580 rear wheel horsepower at 6500 rpm on the dyno. Andy had a customer that wanted 1000 hp on the dyno, but the guy accepted 990 hp. For these extra HP outputs with a LS2 or LS3 you have to make major lower engine upgrades$$$$$.
